OK, and is the second chamber vented? You have two options:

  • Model the whole lot using transient, which could take days (or more) depending on scale.
  • Model steady state assuming the second chamber doesn't influence the flowrate and there is enough pressure & material in the first that it's a uniform flow. 

I can't tell you that, you need to think about it and work out how to defend any assumptions later on.Â
